KINETOGRAPHIC APPARATUS.

SPECIFICATION forming part of Letters Patent N o. 672,71 1, dated .April 23, 1901.

Application filed January 14, 1901. Serial No. 43,230. (No model...)

To @ZZ- wtom, it may concern:

Be it known that I, WILLIAM H. REID, a citizen of the United States, residing at W'ashington, in the District of Columbia, have invented certain new and useful improvements in Kinetographic Apparatus, of which the following is a specification.

This invention relates to apparatus that operates kinetographically, using the term kinetographic in its most comprehensive sense; that is to say, the several forms of the apparatus Write, either permanently or temporarily, successive phases of motion of objects.

Primarily, the apparatus is used to Write in a permanent manner, to record on an image surface, such as a sensitized photographic tape-film, or the like, the successive phases Secondarily, the apparatus is used to exhibit, by projection or by direct View, the successive phases of motion recorded on the image surface, successively in such an intermittent manner as to apparently reproduce the object in motion.

This secondary use of the apparatus is of much more frequent employment than the other use mentioned above, as a record once made on the film, may be used in the projection apparatus a great many times; and, furthermore, the film may have a number of duplicate films made from it, to be used in as many other apparatus.

This invention is a modification of an invention of mine forming the subject matter of an application for letters patent of the United States, filed by me on the First day of October, 1900,- and bearing Serial Number, 31,727.

The object of the present invention is to provide with a movable image surface, such as a film or ribbon, and movable reiiecting means, means for moving the reiiectiug means bodily'in an endless path. In the application above refered to, I set forth means for moving the reflecting' means bodily in a recdiproeating manner; in this application, I provide means for moving the reflecting means in a continuous manner, and bodily during part of its movement.

My invention, broadly stated, consists in using a continuouslyv moving image surface,

and one or more reflect-ing means, arranged to move bodily in an endless path, which reflecting means will canse an image to be reiiected from the image surface onto the screen, or from an object in motion onto the sensitive image film, during' the movement of the image surface for a certain distance; and then the reflecting means will travel through the 6o remaining portion of the endless path, and returning to its former position, will, in the same manner, refiect another image. But I preferably use a series of reflecting means,

which successively reflect the successive images, or phases of motion.

And my invention comprises such further details of construction and arrangement, either separately, or in combination, as will be described hereinafter, and then particu- 7o larly poinled out in the claims, reference being had to the accompanying drawings, in which the numerals of reference indicate the same parts in the several views.

In the accompanying drawings, represent- 'ing certain additional parts.

Figure 6 shows a modification, on the line 6 6 of Figure 7.

Figure 7 is a front elevation of the form oo shown in Figure 6.

Figure 8 is a section of the line 8 8 of Figure 6.

Figure 9 shows in reduced elevation the pulleys of' Figure 6.

Referring now to Figures l, 2, 3 and 4, the reference numeral 12, indicates a suitable base, on which is mounted astandard i3. At

the upper part of this standard are secured a pair of hangers l-L, l, in which is journaled loo a drum 15. Another drum 16, is journaled in supports 17, 17', that are secured on the base.

The tape-film, or other form of image surface, 18, passes from anysuitable supporting means, not shown, over the guide drum 15, thence downwards to the drum 16, by which latter it is actuated, preferablyin a continuous manner. A small roller 19, jonrnaled in the supports 17, 17', is arranged in 4close proximity to the lower part of the drum 16, and serves to retain the film in contact with the drum for a portion of the circumference of the latter. After passing between the roller and the drum, the film passes through a slot 20, in the base. It may then be received by a suitable receptacle, not shown, below the base.

The drum 16, may be rotated by a belt 21 from a pulley 22, that may be driven by any suitable source of power.

A pair of pulleys 23, 24, are secured on a shaft 25, which is mounted in bearing blocks 26, 27, secured on the standard 13, on opposite sides of an opening 13' therein. A similar pair of pulleys 23, 29, are secured on a shaft 30, which is xnountedin bearing blocks 31, 32, secured on the standard 13, on opposite sides of an opening 13". The pulley 23, is arranged in vertical alignment with the pulley 2S, and also the pulley 24, with the pulley 29.

An endless carrier, such as a chain, or a flexible band 33, preferably of metal, runs on the pulleys 23, and 28; and anothersuch band 34, runs on the pulleys 24, and 29.

A rectangular frame 35, is secured transversely to each of the bands 33, 34, and carries a triangular block or frame 36, to which is fastened one of my reflecting means, pref erably a plane reflector or mirror 37. I use preferably a plurality of these reflectors, 33, 39, and 40, arranged in series on the endless carrier formed by the bands 33, 34, and a series of rectangular frames 44, 45, and 46, which carry blocks 4l, 42, and 43, respectively, and support the said reflectors, 3S, 39, and 40. These four reflectors are arranged at an equal distance apart; and are placed at the same angle to the bands 33, 34, preferable at 45. In order to prevent vibration of the bands and reflectors while passing through the rectilinear path adjacent to the lm, the ends of the frame 35, slide in guides 47, 47', that are secu red to the standard 13,hy arms 43.

A gear 49, mounted on the shaft 16', of the drum 16, engages an equal sized gear 50, secured on the shaft 30; and as the four puls leys 23,-26, are each of equal diameter with the pulley 16, the film will travel at the same velocity as the adjacent portions of the bands 33, 34, and the adjacent reiiectors; and also in the same direction as those reflectors. Lugs 51, on each of the pulleys engage apertures 52, in the bands 33, 34, and prevent slip of the bands on the pulleys.

A lens tube L, is secured to the upper part of the standard 13, and contains the projecting lens.

A stationary refiector 03, is secured to the hangers 14, 14', in vertical alignment with the reflector 37, when the latteris in the position shown in Figure 1. This reflector 53, is also in the axis of the lens, and at an angle of 45o therewith, and is parallel with the reflector 37, when the latter is in the said position.

A'shutter 54, mounted on a pinion 55, that is rotatably mounted in the standard 13,serves to cut off the rays passing between the said lens and the reflector 53, during a part of each revolution that it makes. On the said pinion 55, is secured a bevel gear 5G, engaging a bevel gear 57, secured on a horizontal shaft 5S. A vertical shaft 59 has a bevel gear 60, on one end that engages a bevel gear 61, on the end of the said shaft 58. The shaft 25, has one end extended and carries a bevel gear G2, that engages a bevel gear 63, on the lower end of the shaft 59. Thus the shutter is operated from the shaft 25.

In Figure 5, is shown substantially the apparatus set forth in Figures 1, 2, 3 and 4, with the addition of another series of refiectors mounted on a similar endless carrier. In this form I use the standard 13,sup1)orting the endless carrier having the reflectors 37,-40, as described with reference to the said Figures. The film 13, is guided and actuatedin the same manner, and the carrier pulleys from Ithe film drum, as hereinbefore described. Another standard 13, is mounted on the base parallel with the standard 13, and supporis a duplicate of the carrier and reflectors supported by the standard 13; comprising four reflectors 67, 63, 69, and 70, mounted on a carrier running on a pulley system such as previously described with reference to Figures 1, 2, 3 and 4; and, hence, need not he further shown or described. These four refiectors are arranged on their carrier so that when moving` adjacent to the film, they will make an angle of 45o therewith, and will be directly opposite the respectively adjacent refiectors 37, 38, 39, and 40.

A gear 50', secured to the lower shaft 30', of the pulley system on the standard 13, and correspondingtothe gear 59, engages an equal sized gear 71, supported by the standard 13, which latter gear engages the gear 49; thus the reflectors adjacent to the film in each system will move in unison therewith.

Instead of the hangers 14, 14, I provide one or more cross arms 72, which support the guide pulley 15, and the stationary reficctor 53; and also support another stationary reflector 73, that is arranged in alignment with, and parallel to, the reflector 57, when the latter is in the position shown in Figure 5.

The operation of my apparatus is as follows:-

Rays of light from any suitable source, such as an arc light, indicated by the carbons P, N, in Figure 1, are directed by a condenser C, parallel in a horizontal direction, and being intercepted by the refiector 37, will be defiected upwards in a vertical path. They will then be intercepted by the stationary reflector 53, which will deflect them into the lens, by

IOS

IIO

which they will be projected onto a suitable screen, not shown.

Now if both the reflector 37 and the film are at rest, and an image be located on the film so that it is intersected by the rays that are intercepted by the reflector 37 the image would be reflected into the lens and by it projected onto the screen.

Next, suppose the reflector 37, to be in the position indicated by the dotted lines 37X, and to be moved downwards by the carrier to the position in which it is shown, 37. Since it travels in a vertical path between these two positions,it will maintain a constant angle of 45o, with the parallel rays from the condenser C, during this movement, and will deflect the intercepted rays upwards in a vertical path, and upon the reflector 53. And if an image on the film be located opposite this reflector when in the position indicated by 37X, and then the belt 22, be caused to drive the film and carriers, and move the film and reflector downwards in unison, as previously described, until the reflector arrives at the position of 37, it will be seen that the image and the reflector remain immovable relatively, and that rays of light perpendicular to the image are constantly projecting the image onto the reflector; therefore, this pro- -jection will be immovable on the reflector;

that is to say, the points of incidence of the image on the reflector will remain stationary thereon. But, the projection will, of course, be deflected vertically upwards towards the reflector 53; and as these points of incidence on the reflector 37, all travel in a vertical path, the projection will be directed upwards in the same path during this movement of the reflector 37, and therefore will impinge on the stationary reector 57, at the same points for every position of the reflector between the said positions; in fact, for every position of the reflector 37, in its rectilinear path adjacent to the film 18. Consequently, the reflector 53, will deflect the image into the lens in the same path during this entire movement; and the moving image will be held stationary on the screen.

But this result will follow only while the reflector is traveling in its rectilinear path. Vhen the reflector 37, is about at the end of' this movement, the shutter 54, that is so geared relative to the carrier that it makes four revolutions to one movement of the reflector through its endless path, cuts off' the rays between the reflector and the lens for a short interval; during which period the next reflector 3S, is moved by the carrier into the position indicated by 37X. Now the successive images on the film are arranged far apart as are the reflectors on the carrier, and

as the carrier and the lm travel at the same speed, the image that has just been reflected by the reflector 37, has now passed downwards, and the next image on the film will be brought opposite to the reflector 33, now

in the position of 37X; which latter image will be projected onto the screen, and will be held stationary thereon during the interval or period of illumination; that is, between the successive interceptions of the shutter 54, while the reflector is moving th rough its rectilinear path. And then there is another cutting off by the shutter, while the next reflector 39, and the next image on the film, come into position of action. This latter reflector will act as the previous ones; and then after another interception by the shutter, the next reflector 40, and another image on the film are brought into operation. And the next period of illumination will bring the reflector 37, again to the position of 37X, which will then repeat its reflection of an image as in the former case.

In the apparatus shown in Figure 5, the rays falling on the stationary reflector 73, are deflected by it vertically downwards and onto the movable reflector 67, This latter reflector deflects the rays horizontally, which, intersecting the film, fall upon the reflector 37; and the latter reflector will direct them vertically upwards onto the reflector 53, by which they are directed into the lens, and thence onto the screen, not shown, as will be readily understood.

If' an image be located on the film between the now opposite reflectors, 67, and 37, it will be projected onto the screen, providing the reflectors are at rest in the position shown iu Figure 5. But when the drum and gearing move the reflector 37, downwards to the position in which the reflector 40, is shown, and the film downwards in unison therewith, the reflector 67, will be moved downwards to the position inwhich the reflector 70, is shown, and it will travel in unison with the film and reflector 37. Therefore, as the rays impinging on the reflector 67, are all vertical, and as this reflector travels in a vertical path, while moving from the position shown to that of the reflector 70, these vertical rays will impinge on the reflector 67, at the same points and at the same angle during the whole of said movement. The result of' which is that during the said movement, the image will be intersected and thus projected onto the screen by the same rays of' light, instead of a different set of rays for each consecutive position, as is the case with the arrangement shown in Figure l.

When the next reflector, 33, is brought into the position in which the reflector 37, is shown, the next reflector 63, of the other series, will be brought into the position in which the reflector 67, is shown; and the succeeding image on the film will he brought intermediate of these two reflectors, and be projected in the same manner the previous one. And the next reflector 39, will act. in conjunction with the next redector G9, of' the other series; and also the reflector 70, will act in conjunction with the reflector 40.

In Figures 6, 7, 8 and 9, I show a modification of the apparatus hereinbefore described,

IIO

in which f arrange the reflectors in one or more pairs, that are located on opposite sides of the film, as set forth in Figure 5, but which are all mounted on a single carrier, instead of on two carriers, as shown in that Figure.

Two standards 80, and 81, are mounted on a suitable base 79, parallel with each other. A pair of shafts 82, and 83, each have one end journaled in the standards 80, 81, and arranged parallel with each other, and one vertically above the other. The shaft 82, has a pair of pulleys 84, 85, mounted on it; and the shaft 83, has also a pair of pulleys 86, 87, mounted on it: the pulley7 84, being in vertical alignment with the pulley 86, andthe pulley 85, with the pulley 87. An endless flexible band 88, runs on the pulleys 84, and 86; and another such band 89, on the pulleys 85, 87.

An arm 90, extending transversely from one of the said bands to the other, has mounted thereon a pair of blocks or frames 91, 92, that support reflectors 93, 94C, respectively. l pref'- erably use a plurality of such pairs of reflectors, arranged in series, on the endless carriers formed by the bands 88, 89, and the series of arms 90', 902, and 903, which carry blocks 91', 92'; 912, 922; and 913, 923, respectively: and these pairs of blocks support the pairs of reflectors 93', 94'; 932, 9&2; and 933, 94S, respectively. These four pairs of reflectors are arranged in series on the endless carrier, at an equal distance apart, and are all placed at an angle of 450 with the carrier.

ln order to prevent vibration of the carrier when moving adjacent to the film 18, the ends of the arms 90, etc., slide in vertical guides 78, secured to the standards 80, and 81.

One or more cross arms 95, are secured at their ends to the standards 80, 8l, and support a guide pulley 96, and also a pair of stationary reflectors 97, 98; which latter correspond in position and function to the reflectors 53, and 73, shown in Figure 5.

The film 18, passes from any suitable support, not shown, over the guide pulley 96, then vertically downwards and between the reflectors 93, and 94, when they are in the position shown in Fig. 6; then around a guide pulley 99, that is supported from the base; then over another guide pulley 100; and finally around an actuating drum 101, from which it passes downwards through a slot 102, in the base, into any suitable receptacle, not shown, below the base.

The said drum 101, is secured on a shaft 105, journaled in supports 106, 107, that are mounted on the base. This shaft carries a bevel gear 108, that engages a similar gear -109, secured on the shaft 83; by which means the film and the pair of reflectors adjacent to the film are caused to move in unison. A small roller 103, carried by a bent arm 104, that is secured to the standard 106, serves to retain the film in contact with the drum 101, for about half of its periphery.

A pulley 110, is secured to an extension of the shaft 105, which may be rotated by a belt 111, that isdriven from any suitable source of power, not shown.

A shutter 112, secured to a pinion 113, that is rotatably mounted in the standard 80, serves to cut off the rays passing between the lens and the reflector 97, during part of each revolution that it makes. On the pinion 113, is secured a bevel gear 114, engaging a bevel gear 115, that is secured on a short horizontal shaft 116. A vertical shaft 117, has a bevel gear 118, secured on one end that engages a bevel gear 119, secured on the end of the shaft 116. The shaft 82, has one end extended and carries thereon a bevel gear 120, that engages a bevel gear 121, secured on the lower end of the shaft 1l7. Thus the shutter 112, is operated from the shaft 82.

The parallel rays from the condenser C, of Figure 6, are deflected by the reflector 98, vertically downwards and are intercepted by the reflector 94, when the latter is in the position shown, and are caused to intersect the film 18, and then fall upon the reflector 93;

which latter reflector will direct them vertically upwards upon the reflector 97, from which they pass into the lens and then out onto the screen, not shown.

While the reflectors 93, and 911, are passing downwards in their rectilinear path adjacent to the film, and the film is moving in unison with them, and has an image intercepted by the rays passing from the reflector 91, to the reflector 93, the image will be projected onto the screen; in the manner as particularly described with reference to Figure 5. When this pair of reflectors reach the lower part of their movement in this rectilinear path, the shutter 112, intervenes and cuts off the rays from the lens, as in the previously described manner. Then this pair of' reflectors pass to the position indicated by 93', 94', and the next pair 933, 94:3, are brought by the carrier into the upper part of'the rectilinear path adjacent to the film; when the latter pair of' re* flectors will have the next image on the lm located between them, and will project this image onto the screen, in the above described manner.

While 1 have herein shown and described my apparatus as used for the projection of images contained on a transparent tapefilm, if the light and the reflectors between it and the film were removed, and a sensitized film put in place of the image hlm 18, the lens could be focused on a moving object, which would cause a series of images of' the succesw sive phases of motion of the object to be received on the film; that could be made pel manent by proper photographic treatment. The apparatus would have to be enclosed in a light-tight case and a properly timed shutter used instead of the one shown. I

0r my apparatus may beused as a dii ectview machine, by placing the eyes in the path of the rays coming from the reflector 53, (or 97). And, instead of the transparent film,

IOO

IZO

an opaque ribbon or image surface may be used, and, the apparatus not being enclosed, the images would be illuminated by ordinary daylight, which would direct the images onto the reflector 53, (or 97), by reflected instead of by transmitted light.

By the term image surface7 as herein used, I mean either a sensitized photographic surface for receiving andrecordingtheimages of the successive phases of motion, or a su rface on Which such images have been recorded, the latter su rface being either translucent or opaque.

Where the expression bodily movable is herein employed With reference to the movement of the reflecting means, I refer to a movement of the same in which every point is given a movement of translation, that is to say, a movement in which the distance of every point in the refiecting means from every fixed point varies; in contradistinction to a movement of rotation, or of oscillation, in which latter movements every point in the reecting means remains at a constant distance from a fixed axis.
